Ultrasonic Level Meters

Ultrasonic Level Meters
Ultrasonic Level Meters
Product Code : ULM
Product Description

By keeping track of current market advancement, we are providing a distinguished assortment of Ultrasonic Level Meters. This is self-contained device that includes electroacoustic transducer and electronic module. The level meter ULM transmits series of ultrasonic pulses which propagates towards the liquid surface. Manufactured under the visionary guidance of adroit professionals using advance technology and well-checked raw material, the offered range remains in great demand across the market. Further, Ultrasonic Level Meters are thoroughly checked on different quality parameters assuring its impeccability at user's end.

Salient Features :

  • For continuous level measurement of liquids (even if polluted), mash and paste materials in open or closed vessels, sumps, open channels, etc.
  • Configuration and adjustment of measuring range by two buttons
  • Xi version for usage in explosive areas
  • State indication by two LEDs
  • Current (4 ... 20 mA) or voltage (0 ... 10 V) output
  • Options of inverse function (20 ... 4 mA or 10 ... 0 V)
